I drive a bit faster than you do, however.........typically 65-70 for 95% highway traffic.
You've got a good running machine there. 
These W126's are definitely sensitive to the wind. 60 mph gets you significantly better fuel economy than 70 mph. |
The W126's are fuel hogs at speeds 70 +, aren't they? I get only about 24 mpg if I sustain 85 - 90 mph driving all day.
A W124 with a 603 barely burns any, in my experience (about 31 mpg at 80 mph). The combination of the large frontal area, the extra weight, significantly poorer aerodynamics, and the 2.88 differential does not bode well for efficiency. But it is an S-Class,...What the heck.
